Treatment of elderly and frail myeloma patients.

Abstract

Multiple myeloma (MM) is an incurable cancer of older adults. Given the aging population, the prevalence of older adults with MM is expected to further increase over the next decade. Challenges in treating older adults result from the heterogeneity of both aging itself and the disease. Over the past two decades, tremendous progress has been made in improving the outcome in this age group with novel therapeutics, including immunomodulatory drugs, proteasome inhibitors, and more recently anti-CD38 monoclonal antibodies, becoming an integral part of initial treatment. Further improvements are expected over the next decade with novel immunotherapy, including T-cell engagers and chimeric antigen receptor therapies. With additional novel treatments, assessment of patient frailty will become increasingly important in balancing the optimal treatment of patients. In this review, we focus on the treatment of elderly and frail older adults with MM. The first part of our review will focus on pertinent investigations, considerations for treatment initiation and initial risk stratification, including frailty assessment prior to treatment initiation. In the second part, we will focus on the overall goals of treatment and therapeutic options for newly diagnosed and those with relapsed/refractory MM, including novel immunotherapy and supportive care. Lastly, we will end this review by highlighting current knowledge gaps and providing suggestions for future directions to further improve outcomes among older adults with MM.
